Mirror, mirror, on the wall — which sneak-peek movie clip is scariest of them all?

The answer is right here, if you're brave enough to look. We have an exclusive first look at a scene from Relativity Media and director Mike Flanagan's upcoming thriller, "Oculus," ahead of its upcoming South by Southwest debut.

"Oculus" stars Katee Sackhoff and Karen Gillan, best known to genre fans for their work as Starbuck on "Battlestar Galactica" and Amy Pond on "Doctor Who," respectively. Here, the two leading ladies are getting into a scarier game. Gillan plays Kaylie Russell, whose life was changed forever when her brother Tim (Brenton Thwaites) was convicted of killing their parents many years ago. But Kaylie knows better; she knows that it wasn't Tim, but a supernatural force, that was responsible for her parents' deaths — and she's determined to prove it.

How does that supernatural force operate, you ask? That question gets addressed in our exclusive clip, which sees Kaylie walking in a dreamlike state toward a large, haunting mirror. The pulse quickens as Kaylie draws nearer and nearer and nearer to the mirror, until finally...

...yeah, like we're going to spoil the surprise. Watch the clip and try not to jump out of your seat; we dare you. "Oculus" arrives in theaters on April 11, and will also appear at the SXSW Festival as part of the horror-studded midnight lineup. Prepare your nerves accordingly, and try to stay away from mirrors.

Rick Ross and Jeezy showed the hip-hop world that they can do more together as collaborators than they can as rap adversaries. Now, after the release of their highly touted get-together, fans are in for another treat, Rozay reveals.

"We knocked out two records. One is mine, one is his," Ross told "RapFix Live" host Sway when he appeared on Wednesday's show.

Ross, DJ Khaled and MMG's Fat Trel came onto the show to talk about Rozay's brand-new Mastermind album and dissect all that went into recording the LP. The Maybach Music boss says that his hook-up with the Snowman wasn't some grand rap scheme — things just happened to work out.

"It wasn't nothing that was planned. It wasn't planned at all," Ross confirmed. "Me and [Jeezy] ran into each other — my homeys over there, his homeys on the other side of the door — and we just chopped it up," he added of Jeezy, who he had a well-publicized skirmish with backstage at the 2012 BET Hip Hop Awards.

"Where I'm from, if you ain't shed no blood, if you ain't lose no money behind it, it's really small talk," Rozay continued. "When me and him chopped it up, we did it like bosses and said, 'Let's set an example for the next set of entrepreneurs. It's bigger than us. Let's do it for the South, let's do it for the game.' "

The Mike Will Made It-produced track finds the former foes trading bullying bars over pulsating 808s and pounding drums. Ross didn't give much ...

Two months after entering a Chicago facility for an eating disorder, it looks like Ke$hais out of rehab, back to work and, from the looks of her Twitter account, devoid of her signature dollar sign.

"Happy to be back! Feeling healthy & working on tons of new music🐱," the pop singer tweeted on Wednesday night, breaking a nearly month-and-a-half-long silence on the social media site. "I can't thank my fans enough for all the love & support u have given me❤️️"

In addition to dropping the dollar sign, the Warrior singer also changed her Twitter handle from @Keshasuxx to the more demure @KeshaRose -- perhaps a reflection of her more positive view on life post-rehab.

"life is beautiful," she added. "I'm so blessed to have u all."

Ke$ha entered Timberline Knolls Residential Treatment Center on January 3 to treat a long struggle with bulimia and, in her words "to learn to love myself again."

"I'm a crusader for being yourself and loving yourself, but I've found it hard to practice," she said in a statement to MTV News in January. "I'll be unavailable for the next 30 days, seeking treatment for my eating disorder ... to learn to love myself again, exactly as I am."

Her reps have yet to respond to MTV News' request for comment, but considering she also shared a photo of herself on a plane, it looks like she's indeed headed home.

Great news, defenders of the free press: Thanks to journalists from many major media outlets, if you've been dying to see what Justin Bieber looks like while peeing, your prayers have been answered.

Two days after a Miami-Dade County judge relented to the requests of media outlets — submitted under Florida's rather liberal (!!!) public records law, which allows most evidence in a criminal case to be made available after it's been given to a defendant's legal team — video of Bieber submitting to a drug test (you know, peeing) inside a Miami Beach Police Department bathroom was released.

Or, at least that's what it looks like he was doing; after all, that same judge ordered that Bieber's genitals be censored in the video, since his "right to privacy is paramount." So what we're left with is a clip that's basically just 110 seconds of a black box in baggy shorts, though that didn't stop TMZ from posting the footage as "THE MONEY SHOT."

And while the video doesn't reveal much, what's even less clear is what it has to do with Bieber's DUI case ... nothing in it could charitably be described as "evidence." And as such, it's also unclear why so many media outlets were determined to get their hands on the footage.

Unless, of course, their intent was to exploit and embarrass him; because in that case, uh, score one for the First Amendment!

No matter how you look at it, there seems to be no other purpose behind the release of the footage, which ...

Demi Lovato just about broke the Internet on Tuesday after plastering Twitter with photos of her new .

From Fifth Harmony's Dinah Jane Hansen — "Hot," she tweeted with a row of fire Emojis — to Perez Hilton — "Excuse me while I go catch my breath and cry because I can't handle all this fierceness," — Lovatics of all ages went nuts when seeing the singer's surprise 'do.

So when we here at MTV News sat down with Cole Plante, who serves as the house DJ on Demi's Neon Lights Tour, we couldn't help but notice how similar the pair's cuts and colors were.

"I'm not going to make any comment about inspiration but I think somebody might have inspired her to get a certain haircut," the 17-year-old laughed when asked about the striking resemblance. "It was cool, I saw the Twitter picture first that she posted where everyone was freaking out about the hair and I was like, 'Oh, I wonder what it looks like,' and then she came out onstage and I was just like, 'look at that, it's [shaved on] the same side,' so it's pretty cool."

Whether or not he was in fact Demi's muse, Cole says he's a total fan of her new locks.

"She has that, like, really nice, vibrant pink and now I have this red, [which] will eventually turn pink. So at one point on this tour we'll have the same exact hair. I'll just let this come down a couple of inches," he said while exhibiting their difference in length.

Since Jared Leto took a five-year break from acting before his Oscar-winning turn as Rayon in ," in the days since the Academy Awards, everyone is wondering what he'll do for an encore.

As he told MTV News earlier this week, Leto's next move may be to the director's chair; as he's currently "looking for a feature film to direct ... a feature-length narrative."

Of course, for fans of Thirty Seconds To Mars, that's not surprising ... after all, Leto — or, uh, Bartholomew Cubbins — has directed almost all of the band's so-called "short films," including epics like "From Yesterday," and and their recent documentary

And while Leto is searching for a feature film, he may also make a return to his music-video roots ... as he and his Mars mates are kicking around the idea of making another epic. And this one might be familiar to his fans.

"We are, right now, plotting and planning," Leto said. "I would love to do a sequel to 'Hurricane,' maybe that would be 'Bright Lights' or 'Do Or Die,' which could be another single here in the U.S. We're figuring things out. Lots of, as they say, good problems to have."

But before Leto can even begin thinking about Mars' next short film, there's the matter of the band's seemingly endless world tour, which is set to hit the Ukraine next week.

And given the current unrest in the country — and the support Leto expressed for protestors during his Oscar acceptance speech (words that ...
